CLIP FOR MINERS7 LAMPS.

Specification of Letters Patent.

Patented Jan. 9,1912.

To all whom it may concern.'

Be it known that we, GRANT I. Rawson and LLEWELLYN B. SHULTZ, both citizens of the United States, residing at St. Louis, Missouri, have invented a cert-ain new and useful Clip for Miners Lamps, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of our invention is to provide a clip for attaching miners lamps to batteries which will be simple in construction and edective in operation, and which may be easily attached to and detached from the battery.

In the accompanying drawings which illustrate one form of clip in accordance with our invention, Figure 1 is a perspective view; Fig. 2 is a side view, the battery partly in section; and Fig. 3 is a View showing the manner of applying the clip.

Like marks of reference refer to similar parts in the several views of the drawings.

5 represents the battery which is provided with a pair of oppositely arranged contact pins 6. Each of these pins 6 is provided with a head 7 which may be integral, as shown in the drawings, or secured to the pin in any suitable manner. It is important, however, that the heads be rigidly secured to the pins so as not to be detachable.

The clip is formed of a pair of insulating pieces 8 and 9 respectively. Formed in the lower face of the blockY 8 is a recess 10, adapted to receive the ends 11 of a flexible cable 12, leading to the lamp 13. Secured between the blocks 8 and 9 are a pair of spring contact arms 14. These arms 14 are adapted to engage with the contact pins 6. The arms 14 are provided with oppositely arranged inclined slots 15, as best shown by Fig. 1. The clips 14 are held in position by means of bolts 16, passing through the blocks 8 and 9, and secured by means of nuts 17. The bolts 16 also `serve to secure the ends 11 of the cable to' the contact arms 14.

The clip is attached to the battery by turning it into the position shown by Fig. 3, and engaging the inclined slots 15 with the pins 6.

The arms 14 are made of spring metal which tend to move into the position shown in dotted lines in Fig. 2, and hence the faces of the arms are held firmly against the inner faces of the head 7 thus making a good electrical contact. When the clip is moved into its normal position, as shown by Figs. 1 and 2 it cannot be detached from the battery.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent of the United States is:

1. The combination with a member provided with a pair of-projecting terminals, said terminals being provided adjacent to their outer ends with enlarged heads, of a body of insulating material, a pair of spring contacts carried by said body, each of said contacts being provided with a slot for receiving the stem of one of said terminals, said contacts being adapted to bear against the heads of said terminals, and a flexible cable connected with said contacts.

2. The combination with a member provided with headed terminals, of a body of insulating material, a pair of spring contacts carried by said body and adapted to engage with said terminals, said contacts being provided with oppositely arranged slots, and a flexible cable connected to said contacts.

3. The combination with a member provided with laterally projecting headed terminals, of a body of insulating material, a pair of spring contacts carried by said body, terminal engaging means for said contacts, and a flexible cable connected to said contacts.

4. The combination with a member provided with laterally projecting headed terminals, of a body of insulating material, a pair of slotted spring contacts carried by said body and adapted to engage with said terminals, and a flexible cable connected to said contacts.

5. The combination with a member provided with laterally projecting headed terminals, of a body of insulating material, a pair of spring contacts carried by said body and adapted to engage with said terminals, said contacts being provided with oppositely arranged slots, and a flexible cable connected to said contacts.

6. The combination with a member provided with laterally projecting headed terminals, of a body of insulat-ing material, a pair of spring contacts carried by said body and adapted to engage with said terminal, said contacts being provided with oppositely arranged inclined slots, and a flexible cable connected to said contacts.

7. The combination with a body of insulat-ing material, provided with a pocket in its'face, of a flexible cable passing through said block, the strands of said cable terminating in said pocket, a second block of insulating material, contacts arranged between said blocks, and bolts passing through said blocks and electrically connecting the ends of said cable to said contacts.

8. The combination with a member provided with laterally projecting headed terminals, of a block of insulating material, provided with a pocket in its face, a flexible cable passing through said block, the strands of said cable terminating in said pocket, a second block of insulating material, spring cont-acts arranged between said blocks and adapted to engage the said terminals, said spring contacts being provided with oppositely arranged inclined slots, and bolts passing through said blocks and electrically connecting the strands of said cable to said spring contacts.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
